# Runs the PPE aggregation test (CUDA-accelerated prover) across a range of fixture counts
# and prints a results table.
#
# Usage:
# ./bench_ppe_aggregation_cuda.sh
#
# Environment:
# PPE_FIXTURES - path to the fixture file (default: ppe_fixtures.bin)
# COUNTS - space-separated list of counts to test (default: powers of 2, 1..256)
# PPE_SEGMENT_LIMIT_PO2 - log2 of the max cycles per segment (default: 19). Lower values
# reduce peak GPU memory at the cost of more segments / proving time —
# needed on memory-constrained GPUs (risc0's default of 20 OOMs on an
# 8 GB card past n=1). Set to empty to use risc0's default.
#
# Example:
# PPE_FIXTURES=/path/to/ppe_fixtures.bin COUNTS="4 8 16" ./bench_ppe_aggregation_cuda.sh
set -euo pipefail
# This machine's distro CUDA toolkit (12.0) doesn't recognise the RTX 5050's
# Blackwell architecture (compute_120); point the build at the NVIDIA-provided
# CUDA 13.0 toolkit installed under /usr/local instead.
